Title: Cylinder device
Inventor: ISHIWATARI ICHIRO
IPC: F16J15/52
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a cylinder device capable of improving an assembling characteristic for a cylinder main body and a boot. SOLUTION: An outer circumference of an end part of an opening of a cylinder main body 42 is provided with a tapered part 52 of which diameter is gradually decreased toward an outer part of the cylinder main body 42. The extremity end of an annular projection 45 arranged at the extremity end of a boot 44 is provided with a slant surface 53 having a substantial same slant angle as that of the tapered part 52. An outer diameter D2 at the extremity end of the tapered part 52 is set to be larger than an inner diameter D3 of the annular projection 45. When assembled, the tapered part 52 and the slant surface 53 are abutted to each other to attain a centering state between the cylinder main body 42 and the boot 44 and thereafter the boot 44 is pressed against the cylinder main body 42 and the annular projection 45 is fitted to an annular detent 43.  At this time, since they are assembled while the centering characteristic is being kept, an occurrence of strain at the boot 44 is reduced and their assembling characteristic is improved.

Title: Photo semiconductor device
Inventor: ITO MASANORI
IPC: H01L31/108
Filed: 1985-05-25
Abstract: PURPOSE:To decrease the dark current and improve the S/N, by using WSix as the material to constitute the electrode of MSM (metal.semiconductor.metal) photodiode. CONSTITUTION:The MSM photodiode has the electrodes 4 and 5 formed on the active layer 2. WSix is used as the material for the electrodes 4 and 5. In case the barrier height phibn is large, the amount of injected electron in MSM photodidoe is small, but the number of injection hole is large. In case the barrier height phibn is small, the number of injecting hole is small, but the amount of injected electron is large. Accordingly, the condition phibn 2Eg (Eg is the energy band gap) gives the optimum result, and the metal WSix satisfies this condition. By using this WSix the dark current is greatly decreased as compared with the use of Al, etc.

Title: Elevation angle reading device in theodlite
Inventor: FUJII KENJI
IPC: G01C1/06
Filed: 1982-06-30
Abstract: PURPOSE:To obtain an elevation angle reading device whose adjustment is easy, by fixing a detecting device to a coupling part which is coupled to a horizontal shaft in a cylindrical shape. CONSTITUTION:The eccentricity of an elevation scale disk 1 is adjusted by a scale disk fixing member 2, and the disk 1 is fixed to a horizontal shaft 3 by a screw member. In order to obtain a right angle between a vertical shaft and the horizontal shaft 3, the horizontal shaft is rotated with an imaginary point P as a center in a plane of paper as shown by an arc BB. An error in parallel degree between a scale board 1 and a light receiving part 21, especially its index scale, which is caused at this time, is removed, because a coupling member, to which the light receiving part 21 is attached, follows the movement of the horizontal shaft 3. Therefore, an elevation reading device, which can be readily adjusted, is obtained.

IPC: F04D7/08
Filed: 1990-04-27
Abstract: PURPOSE:To alleviate thermal stress appearing on the surface of a pump shaft by providing a heat conductive cylinder at the lower part of the labyrinth seal of a casing cover for enclosing the pump shaft, and gradually heating and raising the temperature of cooling water flowing down within the heat conductive cylinder via the labyrinth seal by means of recirculation water flowing along the external surface of the heat conductive cylinder. CONSTITUTION:Cooling water 10 flows along the external surface of a mechanical seat 7 for the cooling thereof, and returns to the mechanical seat 7 via a heat exchanger 8. Also, a portion of the cooling water 10 passes a labyrinth seal 6 and flows down within a heat conductive cylinder 9 for preventing the leakage of recirculation water 11. In this case, the cooling water 10 in the heat conductive cylinder 9 is gradually heated and the temperature thereof gradually rises in the course of flowing down in the heat conductive cylinder 9, due to the recirculation water 11 flowing along the external surface of the heat conductive cylinder 9. Also, the temperature of the cooling water 10 becomes approximately equal to the temperature of the recirculation water 11 at a position near the outlet of the heat conductive cylinder 9, and a temperature difference from the recirculation water 11 is reduced. Furthermore, a temperature change in the labyrinth seal 6 and heat conductive cylinder 9 becomes small. Consequently, thermal stress appearing on the surface of a pump shaft 4 is alleviated, and the occurrence of a crack due to thermal fatigue can be prevented.
